Based on the removal of the g_dp_display and the movement of the
priv->dp lookup into the DP code it's now possible to have multiple
DP instances.
In line with the other controllers in the MSM driver, introduce a
per-compatible list of base addresses which is used to resolve the
"instance id" for the given DP controller. This instance id is used as
index in the priv->dp[] array.
Then extend the initialization code to initialize struct drm_encoder for
each of the registered priv->dp[] and update the logic for associating
each struct msm_dp with the struct dpu_encoder_virt.
A new enum is introduced to document the connection between the
instances referenced in the dpu_intf_cfg array and the controllers in
the DP driver and sc7180 is updated.
Lastly, bump the number of struct msm_dp instances carries by priv->dp
to 3, the currently known maximum number of controllers found in a
Qualcomm SoC.

Functions in the DisplayPort code that relates to individual instances
(encoders) are passed both the struct msm_dp and the struct drm_encoder.
But in a situation where multiple DP instances would exist this means
that the caller need to resolve which struct msm_dp relates to the
struct drm_encoder at hand.
Store a reference to the struct msm_dp associated with each
dpu_encoder_virt to allow the particular instance to be associate with
the encoder in the following patch.

[why]
vsync_cnt atomic counter increments for every hw vsync. On the other
hand, frame count is a register that increments when the frame gets
actually pushed out. We cannnot read this register whenever the timing
engine is off, but vblank counter should still return a valid number.
This behavior also matches the downstream driver.
[How]
Read the encoder vsync count instead of the dpu_encoder_phys frame
count.

Set the flag vblank_disable_immediate = true to turn off vblank irqs
immediately as soon as drm_vblank_put is requested so that there are
no irqs triggered during idle state. This will reduce cpu wakeups
and help in power saving.
To enable vblank_disable_immediate flag the underlying KMS driver
needs to support high precision vblank timestamping and also a
reliable way of providing vblank counter which is incrementing
at the leading edge of vblank.
This patch also brings in changes to support vblank_disable_immediate
requirement in dpu driver.
Changes in v1:
- Specify reason to add vblank timestamp support. (Rob).
- Add changes to provide vblank counter from dpu driver.
Changes in v2:
- Fix warn stack reported by Rob Clark with v2 patch.
Changes in v3:
- Move back to HW frame counter (Rob).
Changes in v4:
- Frame count mismatch was causing a DRM WARN stack spew.
DPU HW will increment the frame count at the end of
the sync, where as vblank will be triggered at the
fetch_start counter which is calculated as v_total - vfp.
This is to start fetching early for panels with low
vbp w.r.t hw latency lines.
Add logic to detect the line count if it falls between
vactive and v_total then return incremented frame count value.

In TEST_ONLY commit, rm global_state will duplicate the
object and request for new reservations, once they pass
then the new state will be swapped with the old and will
be available for the Atomic Commit.
This patch fixes some of missing links in the resource
reservation sequence mentioned above.
1) Creation of duplicate state in test_only commit (Rob)
2) Allocate and release the resources on every modeset.
3) Avoid allocation only when active is false.
In a modeset operation, swap state happens well before
disable. Hence clearing reservations in disable will
cause failures in modeset enable.
Allow reservations to be cleared/allocated before swap,
such that only newly committed resources are pushed to HW.
Changes in v1:
- Move the rm release to atomic_check.
- Ensure resource allocation and free happens when active
is not changed i.e only when mode is changed.(Rob)
Changes in v2:
- Handle dpu_kms_get_global_state API failure as it may
return EDEADLK (swboyd).

In the current implementation, mutex initialization
for encoder mutex locks are done during encoder
setup. This can lead to scenarios where the lock
is used before it is initialized. Move mutex_init
to dpu_encoder_init to avoid this.

A bit smaller this time around.. there are still a couple uabi
additions for vulkan waiting in the wings, but I punted on them this
cycle due to running low on time. (They should be easy enough to
rebase, and if it is a problem for anyone I can push a next+uabi
branch so that tu work can proceed.)
The bigger change is refactoring dpu resource manager and moving dpu
to use atomic global state. Other than that, it is mostly cleanups
and fixes.

Move mapping of resources to encoder ids from the resource manager to a
new dpu_global_state struct. Store this struct in global atomic state.
Before this patch, atomic test would be performed by modifying global
state (resource manager), and backing out any changes if the test fails.
By using drm atomic global state, this is not necessary as any changes
to the global state will be discarded if the test fails.

Drop the deprecated drmP.h header file, and trim msm_drv.h
to the relevant include files.
This resulted in a suprisingly many edits as many files relied
on headers included via msm_drv.h.
But msm_drv.h is not supposed to carry include files it do not need, so
the individual files have to include what extra they needs.
